Clinical monograph: ndiethyl3toluamide

Diethyl toluamide (DEET) is a widely used insect repellent, primarily effective against mosquitoes, ticks, and other biting insects. It was developed in 1957 and has become the most common active ingredient in insect repellents worldwide. DEET works by masking the scents that attract insects to humans, thereby preventing bites and the transmission of insect-borne diseases.

Indications

  • Prevention of insect bites
  • Protection against mosquito-borne diseases such as malaria and dengue fever
  • Protection against ticks and associated diseases such as Lyme disease

Dosage

Children: For children, use a lower concentration formulation and apply sparingly to exposed skin, avoiding hands, eyes, and mouth. Follow specific product guidelines for age and concentration.

Adults: Apply uniformly to exposed skin or clothing, avoiding eyes and mouth. Reapply as needed, especially after swimming or sweating.

Mechanism of action

DEET's exact mechanism of action is not completely understood, but it is believed to interfere with the insect's ability to detect odors. It is thought to alter the function of odorant receptors in insects, which diminishes their ability to recognize and respond to human body odors and carbon dioxide, both of which attract them.

Pharmacodynamics

DEET has a long duration of action, providing effective protection against insect bites for several hours after application. It is primarily applied topically and is absorbed into the skin, where it can exert its repellent effects. The effectiveness can vary based on the concentration of DEET in the formulation, with higher concentrations generally providing longer-lasting protection.

Pharmacokinetics

DEET is absorbed through the skin and can be detected in the bloodstream after application. It has a rapid onset of action, typically providing immediate protection upon application. The distribution in body tissues is not extensively documented, but it is known to be metabolized in the liver and excreted via urine. The half-life of DEET varies, but it generally remains in the system for several hours, depending on the formulation and method of application.

Adverse effects

  • Skin irritation
  • Allergic reactions
  • Respiratory issues
  • Nausea
